To all who/u it may concern:

lle it known that l, :ilicitano F. Henman, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful improvement in Elevator Attachments for llydreplanes, of which the following;I is a specification.

l/y invention relates to elevators to be attached to hydroplanes wherein the said ele "alter is not only adapted to be shifted to any desired angle but to be shifted bacio Ward or foiwvard horizontally so as to inw crease or decrease the distance between the conter of the elevator and the center of gravity of the hydroplane and its objects are, first, to provide improved means for settling the plane of the elevator to any desired angle, second, to provide means for effectively retainirigg,l the plane of the elevator in the desired angle, and third, to provide means for shiftingv the elevator plane backward or forward without disconnectiiiggI the saine from the controlling' device. l accomplish these several objects by means of 'the device illustrated in the drawings forming' a part of the prese-nt specification Wherein like numerals of reference designate similar parts throughout the said specifications and drawings, and in Which- .Figure 1 is a brolen plan view of the floats or pontoons of a hydroplane with my device attached thereto. Fig. 2 is a vertical sectional view taken on line -X of Fig. 1 looking in the direct-ion indicated by the arrow. Fig. is a broken detailed view of the sliding1 sleeve for maintaining the operating end of the device in a vertical position. Fig. 4l is a broken detailed vievT showing the manner in Which the controln ling shaft is connected to the plane of the elevator.

The numeral 1 is used to designate the parallel floats of a hydroplane connected by means of a hollow Web 2. Parallel supports 3, having slot-s E therein, are rigidly secured to the front ends of the floats 1. Bearings d, to which is secured the plane 5, are slidably mounted Within the slots 3 of the supports 3. A sector G, having' an arcuate slot 6 and teeth 7, is secured to the inner edge of the plane 5. A disk 8 and a pinion 9, secured to a rotatable shaft 10, are adapted to engage the slot 6 and the teeth 7, respectively, of the sector (i. The shaft 10 is rotatably mounted Within an outer bearing 12 and a sleeve 14 which is feathered to the bearings 15 secured to the under surface of the web 2. :i vertical standard l is rigidly secured to the inner oud of the sleeve 1-l and has rotatably mounted therein the vertical shaft 1li provided at its lower end with the gear 1l Which meshes with the ,gear 18 secured to the inner end of the shaft 10. A Wheel 19 rigidly secured to the up per end of the shaft .1G for the purpose of rotating' the said shaft is a seat provided for the operator.

The operation is as follows: By rotating the Wheel 19 the movement thereof is coinniunicated to the shaft- 16 and the' bevel gear 17 which in turn rotates the shaft 10 by means of the bevel gear 18 secured. thereto. As the shaft rotates the pinion 9 secured to the outer end thereof engages the teeth 7 of the sector 6 and causes the plane 5 to which the said sector is secured to rotate on its bearings 4. The difference of the vpitch diameters of the pinion 9 and the teeth of the sector 6 provides a sufficient leverage that the plane 5 may be held in any desired position by means of the Wheel 19. By shifting the Whole device forward it is evident that the base of the angle at which the hydroplane is rising' Will be lene'thened While the altitude of the said angle will remain the same. rlhis will, of course, decrease the angle at which the hydroplane is rising Without altering4 the angle of the elevator plane 5. l have provided this means for altering the rise of the hydroplane quickly to be use'd in case of emergency when there is not time to alter the angle of the plane 5 by means ofthe slower method through the shaft 10 and hand wheel 19. By moving the Wheel 19 forward, the standard and sleeve 1a- Will also move forward in the feathered bearings 15. The forvvard end of the said sleeve will engage a collar 10 secured to the shaft 10, and move the shaft 1G and the disk 8 secured to the front end thereof forward also. rlhe disk 8 beingwithin the arcuate slot 6 of the sector 6, Will move the said sector 6 and the plane 5 forward in the slots 3 of the supports 3. rlihe standard 15 will be maintained in a vertical position by means of the feather 2l which is secured te the sleeve 14 and is slidable Within the bearings 15. y

Having thus described my invention what vI claim as new and desire to secure by Letters Patent isl. An elevator attachment for hydroplanes comprising suitable parallel supports having longitudinal slots in the outer ends thereof; bearings slidably mounted within the slots; a plane rotatably mounted within the bearings; a sector having teeth on the outer edge and an arcuate slot therein, secured to the inner edge of the plane; a rotatable shaft having a pinion adapted to engage the' teeth and a disk adapted to engage the arcuate slot of the sector; and means for moving the rotatable shaft longitudinally.

2. An elevator attachment for hydroplanes comprising suitable parallel supports having longitudinal slots near the' outer ends thereof; suitable bearings slidably mounted within the slots; a plane rotatably mounted within the bearings; a sector secured to the inner edge of the plane and having an arcuate slot therein and teeth on the outer edge thereof; a rotatable shaft having a pinion adapted to engage the teeth and a disk adapted to engage the arcuate slot of the sector; a sleeve slidably secured to the hydroplane and mounted upon the rotatable shaft and adapted to move the said shaft longitudinally; and means secured to the slidable sleeve for rotating the rotatable Shaft.

3. In an elevator attachment for hydro planes, the combination of suitable parallel supports secured to the front ends of the floats of the hydroplanes and having longi tudinal slots near the outer ends thereof; suitable bearings slidably mounted within the slots; a plane rotatably mounted within the bearings; a sector secured to the inner edge of the plane and having an arcuate slot therein and teeth on the outer edge thereof; suitable bearings secured to the hydroplane; a sleeve feathered Within the said bearings and having a vertical standard rigidly secured to one end thereof; a rotatable shaft Within the feathered sleeve having a bevel gear secured tothe inner end and a pinion adapted to engage the teeth and a disk adapted to engage the arcuate slot of the sector secured to the plane; and means secured to the vertical standard of the sleeve for rotating the bevel gear on the inner end of the rotatable shaft.

4. ln an elevator attachment for hydroplanes, the combination of suitable parallel supports secured to the front ends of the floats of the' hydroplane and having longitudinal slots near the outer ends thereof; suitable bearings slidably mounted within the slots; a plane rotatably mounted within the bearings; a sector having an arcuate slot therein and teeth on the outer edge thereof secured to the inner edge of the' plane; suitable bearings secured to the hydroplane; a sleeve feathered within the said bearing and having a vertical standard secured to one end thereof; a rotatable shaft within the bearings having a bevel gear secured to the inner end and a pinion secured to the outer end thereof7 the pinion being adapted to engage the teeth of the sector; a collar on the said shaft adapted to be engaged by the outer end of the feathered sleeve; a disk on the outer end of the shaft adapted to engage the arcuate slot of the sector; and a shaft rotatably mounted within the vertical standard of the sleeve and having a suitable hand wheel at the upper end thereof and a bevel gear adapted to engage and rotate the bevel gear secured to the inner end of the rotatable shaft secured to the lower end of the said vertical shaft.

In witness whereof l hereunto set my signature in the pres-ence of two subscribing witnesses.
